In traditional cloud storage systems, all data is stored in the cloud server, which could lead to major issues including key misuse and privacy data leaking. However, because the traditional cloud storage system depends on centralized storage, a single point of failure could cause the system to fail. With the advancement of blockchain technology, decentralized storage has become more well-known. Decentralized storage can overcome the problem of a single point of failure in typical cloud storage systems while also providing a variety of benefits over centralized storage, including low cost and fast throughput. In this work, focus on data storage and sharing in decentralized storage systems and propose a framework that includes IPFS, an encryption technique, and blockchain technologies. The data holder can distribute secret keys to data users and encrypt shared data location by Blockchain network. In this research contribute to data integrity verification in the blockchain network.

Plastic is a toxic & persistent material available in world. It is generally found to be nearly 5%-10% in Corporation Solid Wastes (CSW) which is a major environmental threat. Present day, industrial plastics are used in our day-to-day life for Various purposes via carry bags in various shops. Plastic made manufacture materials are used for making roofs of temporary kutcha houses and hutments, packaging materials in LDPE & HDPE. Which manufacturing industries, in use of drinking water supply, sanitary appurtenances and in electrical appliance. Industrial plastics based materials product and appliances used for domestic used .The results of Life Cycle Assessment (LCA) of these plastic materials is not satisfactory. Most of people are using of these plastic materials and plastic products after their usage it through on open ground surface and not using reuse. In this paper recycle and reduction in Amount of volume which has become a prominent ecological & environmental problem to utilization in construction. Waste plastic bags & waste plastic materials interrupt the infiltration and percolation of rain water through soil pores and in turn diminish the ground water recharge water surface. Present day, we have present various amount of plastic solid waste in our surroundings. There are so many institutes which after com system researches have come to a conclusion that waste plastics can be used in modifying roads. if we use plastics in road construction, we can reduce the cost of road construction and pollution index of environment to on appreciable extent. Most of researcher use plastics as binder with bitumen. It may give good characteristics to finish-ability, stable to material, good binding property, resistance to water surface and durability with their life period.

The built environment is responsible for 40% of the global energy demand. Efforts are to be made in existing buildings, namely in office buildings, which are statistically more energy consuming than residential buildings. One of the main components of achieving a more sustainable built environment is to improve the performance of the existing building stock by retrofitting to increase the energy efficiency and improve quality of life (Low Carbon Innovation Coordination Group 2012). The retrofit of building envelope can help in saving 50–60% of the buildings’ energy consumption used for HVAC purposes. Secha Sadan is a 50 year old government office building in Bhubaneswar. Proposing a building envelope retrofitting for this structure will not only help in reducing the energy consumption of this structure but would also shed light on how this can be implemented in other such existing government office buildings in Bhubaneswar. The existing envelope has been documented and analyzed using U-Value calculations and simulation softwares like OPAQUE and Form it. A number of envelope retrofitting techniques have been studied and shortlisted through literature, desktop and case studies to propose the best strategies. It was found that 40% savings can be achieved by the retrofit strategy implemented. Also the live proposal of an extension of the existing block to accommodate a new division has been taken into consideration. An attempt has been made to design this block appropriately keeping in mind the required thermal performance standards.

Emotional Intelligence analysis is a tool used to understand and analyse a person's emotions based on facial recognition. It uses advanced algorithms to detect and interpret facial expressions and provides detailed information about a person's emotional state. The tool used in the number of the current face, including the person's smile and the specific behaviour that emerges. This data is then processed and analysed to create an index bar from depression to happiness that provides an overview of the emotional state of the person being examined. The model Emotional Intelligence Analysis is designed to be versatile at the same time, making it ideal for use in groups or public places where searching and interpreting emotions is difficult.In addition, the device captures the emotions of mask wearers, as well as easy in Multiple faces Emotion Recognition. Overall, emotional analysis is a powerful tool for understanding and interpreting a person's emotional state. Using facial recognition, the device can provide a better understanding of a person's emotions, making it useful for many applications in psychology, medicine, and business.

All over the world Drowsiness has been the significant cause of horrible accidents which is causing deaths and fatalities injuries. Day by Day fatal injuries numbers are increasing globally. From the past many years, researchers have concluded drivers with a lack of sleep and more tiredness which causes drowsiness of the driver. This paper shows a new experimental model is designed for detecting drowsiness of driver is presented to reduce accidents caused by this problem which increases transport safety. In this work, two ways are used to detect the drowsiness of a person effectively. First Driver face is captured and eye retina detection and facial feature extraction are done and blinking values are calculated then threshold values are set. The result from both methods is taken as input for taking the final decision and alerting the driver. Nowadays, road accidents have become one of the major issues. The major road accidents are caused due to drowsiness, drunken, and rash driving. This is the reason, every year the number of road accidents is increasing especially by cars. Due to drowsiness, drivers become less active while driving. This paper represents to build a system for Drowsiness Detection and Warning for automobile safety and accident prevention. We are using eye detection, drowsiness detection, and eye blinking pattern detection with the help of machine vision-based concepts. In order to detect fatigue or drowsiness, web-camera has been used which points directly towards the driver’s face and detects the eye movement of the driver.

A microgrid is a localized group of electricity sources and loads that normally operate connected to and synchronous with the traditional wide area synchronous grid (macrogrid), as the number of DC-generating renewable energy sources is higher as compared to AC-generating sources, lesser converter units are required. This increases the overall efficiency of DC microgrid. A DC micro grid system is using a power network that enables the introduction of a large amount of solar energy using distributed photovoltaic generation units. This research deals with the design and performance analysis of a DC microgrid with battery-supercapacitor energy storage system under variable supercapacitor operating voltage. MATLAB 9.4 is using to implement the model and analysis.
